In 1925, Emil Filla reached a point in his work characterised by unprecedented expressive breadth and the convergence of two parallel lines of modern painting: one emerging from Constructivism and abstraction and the other reverberating with impulses of synthetic Cubism. While Filla dealt almost exclusively with the still life, he continued to examine its artistic possibilities and always interpreted it with a new expressivity or a different painterly style. The listed canvas is one such work and reflects Filla’s remarkable virtuosity in its use of colour, as well as the artist’s divergence from the Cubism of Picasso. Visually unusual, this attractive painting of high aesthetic quality captivates at first glance with the bold texture of the impasto deposits of paint that give it a haptic resonance. Within the bright palette, each of the objects depicted is assigned its own approach to colour. The scene is dominated by a sliced, three-dimensional yellow lemon, the shades of which set the tone for the entire composition. It also features a textured fish and a plate depicted from above, a green bottle viewed from the front, and a Cubist-style square glass that allows the observer a view of the interior from above. The background is divided into several geometric segments that interact dynamically thanks to the refracted colours. The pastel pink that appears at numerous points in the composition unites the scene as a whole and adds a fitting dose of fragility. Still Life with Lemon radiates an extraordinary painterly confidence and internal rhythm through its interplay of colours and shapes, suggesting that Filla was capable of navigating the realm of the concrete and tangible while making a universal gesture towards abstract expression.  The authenticity has been confirmed by the Filla Foundation and the painting will appear in a forthcoming inventory of the artist’s works.

Srp is attached: “[...] Filla squeezed his entire life into this smaller format, which he managed to illuminate with vibrant colours, giving it an extremely lively, pulsating sense of light. [...]
